I'm not exactly sure what you are asking for?
LVM2 provides preconfigured automake & autoconf files purely for the purpose
of very simple checkout and build without the need to install those packages.
On the other hand - if you have those packages installed - you could very
easily reconfigure whole package to use those version from your system.
The most typical way should be to run 'autoreconf'.
As of now - some very old automake tools are used to create those git files,
I think it comes from Fedora 14.
